According to Sky Sports news, Dortmund is close to signing Manchester City teenager Hittens.
Reports claim that Hittens has arrived in Germany and he will complete his transfer to Dortmund.
If the transfer takes place, Manchester City can get a compensation from Dortmund.
Hittens will be the latest England teenager to join Dortmund after the Hornets signed Sancho from Manchester City.
And this summer, midfielder Bellingham moved from Birmingham to Dortmund.
Hittens spent his 16th birthday last month. He is currently a member of the England U16 youth team and he was also selected for the U17 representative team.
